Roof-type stock-piling - Hellwagstraße 6 - 8, Vienna, Austria

This property is part of a massive apartment building with a flat roof on Hellwagstraße, Universumstraße and Kampstraße. It was constructed in 1980.
6 stairwells connect 240 medium and small apartments. The apartments have good thought out and efficient floor plans. A series of horizontally positioned loggia-bands between the closed exterior walls provide structure to the facade.
41 new apartments are designed as roof stockpile following the principle of the existing building. The new roof structure consists of a rhythmical series of vertical and inclined exterior wall surfaces with recessed terraces in between. Two front facing wood laminate strips in the parapet area and at the top edge of the roof connect these different elements. The lower strip forms the terrace railing; the upper strip provides sun protection for the terraces. This horizontal layout creates a unified structure as new finish for the massive building block.
